UNITED STATES PATENT OEEICEe BENJIMAN FRANKLIN WILLIAMS, OF NORWOOD, COLORADO.

SlCKLE-HEAD.

SPECIFICATION forming part of Letters Patent No. 637,951, dated November 28, 1899.

To all whom t may concern:

Beit known that I, BENJIMAN FRANKLIN WILLIAMS, a citizen of the United States, residing at Norwood, in the county of San Miguel and State of Colorado, have invented a new and useful Improvement in Sickle-Heads for Mowing-Machines, of which the following is a specification.

My invention relates to improvements in sickle-heads in which an oscillating shuttle working in a plate connected to the sickle constitutes the framework of the invention.

The object of my invention is to providea sickle-head which will allow the sickle to be adjusted to the cutting of any variety of grass without creating the strain incident to other kinds of sickle-head connections on the pitman and crank-wheel. I attain this object by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 is a vertical section of the entire invention; Fig. 2, a top View of the entire invention.

Similar letters refer to similar parts throughout both views.

The plate d, connected to the sickle by the rivets f, constitutes the framework of the invention. In the plate d works the shuttle o, working on hardened-steel bearings at the points e.' The shuttle c is composed of the finest machine-steel, tempered so as to render it as resistible as possible to the friction of the bearings.

The bearings p c are formed by the setscrew b extending through the plate d on the rear end and a piece of steel welded into the plate d on the front end.

The set-screw I) screws through the plate d and makes it possible to regulate the tightness of the shuttle c against the bearings `2J e. Asafety-fap is attached to render it more secure.

The set-screw b is composed of a very high grade of machine-steel.

The plate d is composed of Norway iron.

I am aware that pitman a has been used with the style of connection shown in the drawings and fastened in different ways, and therefore I do not claim any invention on pitman; but

What I do claim as my invention, and desire to secure by Letters Patent, is-

In a sickle-head joint,a rigid member firmly secured to the sickle-bar, two projections on said rigid member, one of said projections having a rigid pivot extending,r therefrom, an adjustable pivot extending from the second projection, a movable member supported by these pivots, and having two pivots eX- tending from the sides at right angles to the line of suspension, a pitman, and two plates secured to the sides of said pitman and adjustably engaging the pivot-points of the movable member, substantially as described.

BENJIMAN FRANKLIN WILLIAMS,
